YES YOU CAN paint them in Enamel Paint..i use Rust-oleum or Krylon rattle can spray paints & primer and they dont take long to dry at all. make sure u sand and clean the parts..i myself will soak them in 99% Isopropyl Alcohol for 2 minuets then wash in warm soapy water, rinse well..and if you like Testors Model Master paints then use them they nothing wrong with Testors paints..i have some my self...
